But AI models are not limited to specific countries, they can be downloaded and run anywhere. Train in Japan (unrestrictive rules), then use in US.

I didn't mean to imply that they aren't real.

I just wanted to say that laws are subject to change.

I always found it fascinating how universal copyright law is. Countries that can't agree on almost anything else have all deigned to give (okay, now that it's 2024, we can't use the rodent anymore, what's the new symbol of eternal copyright?) holy sanction for decades at a time.

Much of the heavy lifting is done by treaty-- not so much that anyone is asking legislatures directly to establish and extend copyright, but that it comes part-and-parcel with other international obligations.

Without the weight of such treaties, I wonder how many countries would do without an IP regime at all, especially if they don't see any IP-related export opportunities, so copyright and patent merely limits their ability to make cheaper versions of foreign goods.
